Abstract

The invention belongs to the fixture and gauge field and discloses a small end cover surface roundness dial plate type measuring instrument. The small end cover surface roundness dial plate type measuring instrument comprises a base; the base is horizontally provided with an elastic clamping plate through a vertical main upright rod; the elastic clamping plate is provided with a dial indicator; a supporting seat is arranged beside the main upright rod; the upper surface of the supporting seat is provided with a plurality of supporting blocks for limiting an end cover to be measured; and the pointer of the dial indicator points to the supporting seat. The small end cover surface roundness dial plate type measuring instrument of the invention has the advantages of effective and reliable detection, being intuitive, high efficiency, low error rate, no technical requirements for operation personnel, being conducive to manual operation, little possibility of causing fatigue, high work high precision, low manufacturing cost, easiness in manufacture and processing, easiness in spare part replacement and high interchangeability.

Description

Technical field [0001] The invention belongs to the field of fixture checking tools, and is specifically a small-scale end cover surface roundness dial gauge. Background technique [0002] In the manufacturing process of commonly used small commercial or vehicle generators or engines, the end covers of generators or engines are mostly made of metal casting. In order to ensure rigidity and reduce weight, they are mostly made of aluminum alloy casting; in the casting process Generally, it is necessary to leave a machining allowance, and then perform cutting processing to become a finished product. [0003] In order to meet the assembly requirements of the end caps, the relevant dimensions of the end caps need to be controlled. Therefore, it is necessary to measure the dimensions after the manufacturing is completed to ensure compliance. Such as figure 1 Most of the end cap 10 shown is a regular circle in appearance. In order to ensure that the assembly size is qualified, a dimension...
